i don't really have one
the words a brainless person uses when they’re too lazy to make a decision, especially after being questioned about what they like best in a situation they didn’t even bother to think about
'I don't really have one', after being asked what they like most about the party they skipped
'I don't really have one', when asked their favorite part of the game they couldn’t even watch
'I don't really have one', when asked what they like about the movie they didn’t show up to
